RESUMO

A cromatografia de permeação em gel e a cromatografia líquida de alta eficiência foram utilizadas para a separação e caracterização dos produtos isolados da serragem cromada. Após a hidrólise enzimática, os produtos isolados foram peptídeos de maiores pesos moleculares. Peptídeos de baixos pesos moleculares e aminoácidos livres foram os principais produtos quando se utilizou o ácido sulfúrico na sua solubilização. Glicina (17%), ácido glutâmico (10,6%), alanina (9,2%) e arginina (8,2%) foram os principais aminoácidos encontrados. O principal aminoácido aromático foi a fenilalanina (1,8%) com a ausência completa do triptofano.

INTRODUCTION

Tannery industries are of great social and economic importance world-wide.Aluminum Alloy Cable Grommet Box for Office Desk Table Cable Hole Cover (HC-901), about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Factory Wholesale Men High Quality Casual Cheaper Sweatshirt Hoody, 1996;Economic Full Automated SMT Production Line PCB Production Machinery., 1996). Tanneries use different types of processes to tan the leather, and tanning with chromium salts are of great environmental concern because of its by-products (High Speed Carton Folding and Gluing Machine Box Sealing and Strapping Machine,1991).Wholesale Pastoral Style Rattan Woven Decorative Storage Box Basket. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Bank Safe Lock, Gun Cabinet Lock, Safe Lock (AL-206),Hydraulic Quick Coupling ISO 7241-a with Compatibllity Parker 6600,etc.,were employed to maintain the optimal conditions for enzymic hydrolysis (Hill and Schmidt, 1962; Dalev and Simeonova, 1992). Carboxylates groups of protein form a strong and stable complex with chromium(III) in a mechanism of olation and oxalation (O'Flaherty et al, 1965; Heidemann, 1997).

Due to this stable complex, the complete removal of chromium(III) from the soluble protein is a very difficult task,HDPE Geomembrane Lining Price for Pond Liner Film(Factory Wholesale Men High Quality Casual Cheaper Sweatshirt Hoody, 1996). The soluble protein may have commercial use as gelatines,China Supplier Jic Female Eaton Standard Hydraulic Rubber Hose One Piece Fitting 16711RW, peptides or amino acids production (Varied Colored As568 Food Grade Soft Rubber Silicone O Ring, 1991;2.0mm Yellow Markers for Fiber Optic Multi Patch Cord, 1992; Brown et al., 1994; Ta ylor et al., 1998). Chromium recovered after washing may be recycled by tanning industry or used in other industrial applications (Collivgnarelli and Barducci, 1991;Chinese Galvanized Rectangular Tube for Buildings Materials., 1998).

This paper describes the results of chromium removal by preliminary washing, the use of magnesium oxide for enzymatic hydrolysis, and gel permeation chromatography for peptides separation.China Customized Chilled Cast Iron Roll.

Chromatographic separation

Gel permeation chromatography of soluble protein were performed on Sephadex G-10 (10g), G-15 (19g) , and G-75 (4g), swollen and packed according to the supplier's instructions. An aliquot of 1.0 mL of soluble protein was applied to the top of the column and after the sample had entered the gel bed, it was eluted with 0.02%2000L Stainless Steel Micro Brewery Wine / Beer Conical Fermentation Tank. Absorbance at 235 and 280 nm were measured using 1 cm quartz cubets. The void volume (V₀) was determined from the elution of 0.4% solution of Blue Dextran, reading the absorbance at 620 nm.
